What clearing your cache does

Your cache is a folder on your computer or phone that stores copies of websites, images, and files you have already visited. When you visit a website again, your device loads those stored copies instead of downloading them fresh from the internet — which makes the page load faster. Clearing your cache means deleting all those stored copies.

Think of it like a notebook where your browser writes down "I saw this picture at this address on this date." Over time, the notebook fills up. Clearing the cache is tearing out those pages so your browser starts fresh.

Key Takeaways

  • Your cache stores copies of websites and images you have visited so pages load faster the next time.
  • Clearing your cache frees up storage space and can fix websites that are not displaying correctly.
  • The steps to clear your cache are different in Chrome, Safari, Firefox, and Edge — each browser has its own menu.
  • Clearing your cache will log you out of most websites, so you will need to sign back in.
  • You can set your browser to clear the cache automatically every time you close it, or leave it alone if storage space is not a problem.

When clearing your cache actually helps

Clearing your cache solves real problems in a few situations. If a website is showing you an old version of a page — broken images, outdated information, or buttons that do not work — clearing the cache forces your browser to read the current version instead of using the stored copy. This fixes the problem most of the time.

Clearing your cache also frees up storage space on your device. If your phone or computer is running low on storage, clearing the cache can give you back gigabytes of space. On a phone with limited storage, this can be the difference between being able to install an update and not being able to.

Some people clear their cache for privacy reasons — it removes the record of which websites you visited and when. This does not hide your activity from your internet provider or from the websites themselves, but it does remove the local record from your device.

How to clear your cache in the most common browsers

In Chrome: Click the three vertical dots in the top right corner. Select "Settings." Click "Privacy and security" on the left side. Click "Clear browsing data." A window will pop up. Make sure "Cached images and files" is checked. Choose the time range (usually "All time" if you want to clear everything). Click "Clear data."

In Safari on Mac: Click "Safari" in the top menu bar. Select "Settings." Click the "Privacy" tab. Click "Manage Website Data." Select the websites you want to remove, or click "Remove All" to clear everything. Click "Remove" or "Remove All."

In Safari on iPhone or iPad: Open "Settings." Scroll down and tap "Safari." Scroll down and tap "Clear History and Website Data." Choose the time range. Tap "Clear History and Data."

In Firefox: Click the three horizontal lines in the top right corner. Select "Settings." Click "Privacy & Security" on the left. Under "Cookies and Site Data," click "Clear Data." Make sure "Cached Web Content" is checked. Click "Clear."

In Microsoft Edge: Click the three horizontal dots in the top right corner. Select "Settings." Click "Privacy, search, and services" on the left. Under "Clear browsing data," click "Choose what to clear." Make sure "Cached images and files" is checked. Click "Clear now."

What happens after you clear your cache

After you clear your cache, websites will load slightly more slowly the first time you visit them, because your browser has to read everything fresh instead of using stored copies. This slowdown is usually not noticeable — it might add a fraction of a second. After that first visit, pages will load at normal speed again.

You will be logged out of most websites. The next time you visit Gmail, Facebook, your bank, or any other site where you have an account, you will need to sign in again. This is because the login information was stored in your cache along with everything else.

If you have saved passwords in your browser, clearing the cache does not delete them — they are stored separately. Your browser will still offer to fill in your username and password when you sign back in.

Whether you should clear your cache regularly

You do not have to clear your cache regularly unless you have a specific reason. If your device has plenty of storage space and websites are displaying correctly, leaving your cache alone is fine. The cache is designed to be there — it makes your browsing faster.

If you share a device with other people and want to remove the record of which websites you visited, clearing your cache is one step — but it does not hide your activity from the device owner or from your internet provider. If privacy from other users is important to you, using your browser's private or incognito mode is a better choice, because it does not store a cache at all while you are using it.

You can set your browser to clear the cache automatically every time you close it. In Chrome, go to Settings > Privacy and security > Clear cookies and site data when you quit Chrome and toggle it on. In Firefox, go to Settings > Privacy & Security > Cookies and Site Data and select "Delete cookies and site data when Firefox is closed." This way you do not have to remember to clear it manually.

Cache versus cookies versus browsing history

These three things are related but different, and clearing one does not clear the others. Your cache stores images and files to make pages load faster. Your cookies are small text files that websites use to remember you — they store login information, preferences, and tracking data. Your browsing history is the list of websites you have visited, which appears in your browser's history menu.

When you clear your browsing data, most browsers let you choose which of these three to delete. You can clear your cache without clearing your cookies, or clear your history without clearing your cache. If you want to remove all three, make sure all three boxes are checked before you click "Clear."

Frequently Asked Questions

Will clearing my cache delete my passwords?

No. Passwords saved in your browser are stored separately from your cache. Clearing your cache will log you out of websites, but your browser will still have your saved passwords and will offer to fill them in when you sign back in.

Does clearing my cache make my device faster?

Not noticeably. Clearing your cache might free up storage space, which can help if your device is very full, but it will not make your device run faster overall. In fact, websites may load slightly slower the first time you visit them after clearing your cache, because your browser has to read everything fresh.

Can I clear my cache on my phone?

Yes. On iPhone, go to Settings > Safari > Clear History and Website Data. On Android, open Chrome, tap the three dots, go to Settings > Privacy > Clear browsing data, and make sure "Cached images and files" is checked.

What is the difference between clearing cache and clearing cookies?

Your cache stores images and files to make pages load faster. Your cookies store login information and website preferences. Clearing your cache frees up storage space and fixes display problems. Clearing your cookies logs you out of websites and removes tracking data. Most browsers let you clear them separately.

If I clear my cache, will websites know I visited them?

Yes. Clearing your cache removes the record from your device, but the websites themselves still have records of your visits on their servers. Your internet provider also has records of which websites you visited. Clearing your cache only removes the local record from your computer or phone.
